Hi- Continued. I shut down the Pbook, removed the battery and unplugged the adaptor cable. And waited about an hour for that capacitor to discharge. Then I reconnected the power adaptor and pressed the start button. The PowerBook started normally, chimes and all. I got a message about an incorrect time, but while I was reading the message the clock reset to correct time. And the same results should be seen on any desktop Mac without a PRAM battery or with a dead one. In other words, no disaster, minor inconvenience. This was easiest to demonstrate on a portable, but through the years I've used desktops with dead batteries (Mac and dark side) with similar outcomes. After a while, it's a big PITA, but that's all.
